What is the correct syntax for json traversal and displaying data in a view - Rails 5?

I have a little problem displaying all values ​​in the json response from api, especially around the rullings part where some of the values ​​are in an array and there are arrays in them.

I've had some success displaying data, but I'm struggling when it comes to arrays
I've searched many related questions, but many seem to focus on generating the json as supposed to display it.

Below is what I have done so far, and hopefully I make sense:

Controller:

class MtgController < ApplicationController
  require 'net/http'
  require 'json'

  layout 'admin'

  def index
    @message = "Mtg Api"

    if params[:search].present?
      url = 'https://api.magicthegathering.io/v1/cards?name='+ params[:search]
      uri = URI(url)
      responce= Net::HTTP.get(uri)
      @json = JSON.parse(responce)
    end
  end
end

      

        
        
        
      

    

View

<% @page_title = "Magic the Gathering" %>

<h1>Magic the Gathering</h1>

<div class="search">
  <%= form_tag(mtg_index_path, :method => :post) do %>
  <table>
    <tr>
      <td><%= label_tag(:search) %></td>
      <td><%= text_field_tag(:search, params[:search]) %></td>
    </tr>
      <td>&nbsp;</td>
      <td><%= submit_tag("search") %></td>
    </tr>
  </table>
  <% end %>
  <%
  if params[:search].present?
    @json["cards"].each do |json|
  %>
  <p>
    Name <%= json['name'] %><br>
    manaCost <%= json['manaCost'] %><br>
    cmc <%= json['cmc'] %><br>
    colors <%= json['colors'] %><br>
    colorIdentity <%= json['colorIdentity'] %><br>
    type <%= json['type'] %><br>
    types <%= json['types'] %><br>
    subtypes <%= json['subtypes'] %><br>
    rarity <%= json['rarity'] %><br>
    set <%= json['set'] %><br>
    setName <%= json['setName'] %><br>
    text <%= json['text'] %><br>
    artist <%= json['artist'] %><br>
    power <%= json['power'] %><br>
    toughness <%= json['toughness'] %><br>
    layout <%= json['layout'] %><br>
    multiverseid <%= json['multiverseid'] %><br>
    imageUrl <%= json['imageUrl'] %><br>
    originalText <%= json['originalText'] %><br>
    rulings: <br>
    <%= json['rulings'] %><br>

    <% json['legalities'].each do |play|%>
      legality <%= play['format'] %> <%= play['legality'] %><br>
    <% end %>

    id <%= json['id'] %><br>
  </p>
  <% end %>
  <% end %>
</div>
